With great stacking comes great conductivity: Trifluoromethylated corannulenes are unexpectedly strong electron acceptors in solution. Even a polycrystalline film of 1,2-(F3C)2-corannulene (top structure and curve in the plot) exhibits conductivity three orders of magnitude higher than that of pristine corannulene!
